Hello everyone.
The other day I was listening Damien Rice´s song "My favorite faded fantasy" Btw, it´s amazing.
Anyway. He says : I could love you more than life If I wasn´t so afraid.

I thought that sentence was a second conditional sentence, but I did my researh and I found out that when you use the second conditional you should use the subjunctive.

If so, What is the right sentence?
I could love you more than life If I weren´t so afraid OR
I could love you more than life If I wasn´t so afraid

I heard that native speakers tend to say "I was" instead of "I were"
Which one does sound more natural?

Answer

In informal contexts (spoken or written), both sound equally natural to me.  In formal writing, I would use "weren't."

Answer

I definitely think in the context of who he is singing to it makes sense and sounds natural to say "wasn't" (more informal) but honestly I wouldn't personally think it was/were ;) weird if he said "weren't".
